This video discusses the stereochemistry of organic compounds that are represented as fischer projections. It shows you how to identify the chiral carbon centers also known as stereocenters in a fischer projection and how to calculate the number of stereoisomers in addition to assigning R and S configuration to each chirality center. This video provides a lot of examples and practice problems on how to name organic compounds using fischer projections. It also shows you how to classify two compounds as diastereomers, meso compounds, enantiomers, or constitutional isomers.

Organic Chemistry on Khan Academy: Carbon can form covalent bonds with itself and other elements to create a mind-boggling array of structures. In organic chemistry, we will learn about the reactions chemists use to synthesize crazy carbon based structures, as well as the analytical methods to characterize them. We will also think about how those reactions are occurring on a molecular level with reaction mechanisms. Simply put, organic chemistry is like building with molecular Legos. Let's make some beautiful organic molecules!
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps.

It's the night before the big game! You're carbo-loading! Wait, what are carbs? Did you know that sugar is a carbohydrate? You didn't?! Well, you'd better watch this, my friend. We will cover all the monosaccharides in their linear and cyclic form. That'll get you up to speed. Now get some sleep! You'll need to be rested if you're going to beat those kids from Khan Academy in the morning.

This organic chemistry video tutorial explains difference between chiral molecules and achiral molecules and how to find them by drawing a line of symmetry. It shows you how to identify the chirality centers or carbon atoms with 4 different groups as well as determining the number of stereoisomers using the formula 2^n where n is the number of stereocenters or asymmetric carbon atoms. This video also helps you to identify a pair of meso compounds which are identical to each other and a possess an internal plane of symmetry. It also discusses how to find a pair of enantiomers which are non-superimposable mirror images of each other such as your left hand and your right hand. Enantiomers lack an internal plane of symmetry. This video contains plenty of examples and practice problems.

Part 1 of my series on how to determine R and S configurations in the four possible situations at your chiral center. Hopefully you guys like my trick/approach at doing it. I actually realized this while tutoring a student on it.

Facilities.
Facilities for business continuity may include alternate workspace equipped for continuation of business operations. Alternate facilities may be owned or contracted including office space, data center, manufacturing and distribution.
Systems.
Systems for emergency response may include detection, alarm, warning, communications, suppression and pollution control systems. Protection of critical equipment within a data center may include sensors monitoring heat, humidity and attempts to penetrate computer firewalls.
Every building has exit routes so people can evacuate if there is a hazard within the building. These exit routes should be designed and maintained in accordance with applicable regulations.

Business continuity resources may include spare or redundant systems that serve as a backup in case primary systems fail. Systems for crisis communications may include existing voice and data technology for communicating with customers, employees and others.
Equipment.
Equipment includes the means for teams to communicate. Radios, smartphones, wired telephone and pagers may be required to alert team members to respond, to notify public agencies or contractors and to communicate with other team members to manage an incident.
Many tools may be required to prepare a facility for a forecast event such as a hurricane, flooding or severe winter storm.
Materials and Supplies.
Materials and supplies are needed to support members of emergency response, business continuity and crisis communications teams. Food and water are basic provisions.
Systems and equipment needed to support the preparedness program require fuel. Emergency generators and diesel engine driven fire pumps should have a fuel supply that meets national standards or local regulatory requirements. That means not allowing the fuel supply to run low because replenishment may not be possible during an emergency. Spare batteries for portable radios and chargers for smartphones and other communications devices should be available.
Funding.
Worksheets.
